YES you can install the "Article Sharing for JMS" in the slave site.
I have told you that you have to check that you install it in a slave site and not on a "standalone" joomla because it require to have JMS present.
If you want that we configure and install everything on your server, this is also possible with our billable support that you can order at

If you are not able to re-install the "Article sharing for JMS" in the slave site, you can all use the JMS tools to install the "Article Sharing for JMS" in the slave site.
You have to go in JMS tools, select the slave site and in the "components" tabs, use the install on the "article sharing".
